landfill gas control Articles

The use of landfill gas as a source of renewable energy is increasing. For environmental and safety reasons, the owners of the waste storage sites have to strictly monitor and control the construction, operations, and emissions generated. Sulzer offers solutions to control these emissions within the limits given by the government. Landfill gas is similar to natural gas, but it is created by ...

Purpose of Document The purpose of this document is to provide standardized procedures for California Integrated Waste Management Board (Board) inspectors to use when performing landfill gas (LFG) monitoring during routine disposal site inspections. The standardization of procedures is intended to produce an acceptable level of confidence in the monitoring. This document presumes that each ...

Type HOFGAS®- Sparky S Commissioning 2002 Site Marley (GB) Situation The Marley landfill site in England is systematically degassed in order to meet the stringent local regulations. Marley is a proportionally small landfill site and does not deliver enough gas for energy generation. Consequently, the ...

A major US waste handling company operates a large landfill in Florida, and in 1992, when Hurricane Andrew struck southern Florida, the landfill saw a huge increase in the amount of C&D waste. Shortly after this, the levels of H2S started dramatically rising. This company evaluated several technologies for the removal of H2S, which was estimated to be as high as 5000 ppmv, with up to 2-3 tons/ ...

Based on local legislation requirements ( reduction of green house gas emissions ) the ...

Infrared absorption Infrared absorption is usually the preferred method for measuring methane and carbon dioxide. Most gases absorb radiation in the infrared region. The wavelength of radiation that is absorbed is determined by the natural vibration frequencies of the molecule. These natural frequencies will depend on several factors. Thus different gas molecules have different natural ...

Type Degassing installation HOFGAS®-C7/1000 + HOFGAS®-Ready 600 Commissioning May 2002 Site Landfill of Iles Les Meldeuses Situation The landfill is being degassed by a plant we supplied in 1998. For the planned extension phase Hofstetter France Sarl was committed to work out a concept for the enhancement ...

Type Degassing installation HOFGAS®- Ready 600 Commissioning January 2002 Site Landfill of Bovenfeld (NL) Situation The 9ha large landfill site Bovenfeld is located 150km northeast of Amsterdam. The resulting landfill gas has to be cleaned, in accordance with the local legislation. A degassing ...

For over 43 years Catalytic Products International has designed and manufactured specialized oxidation systems for use in controlling process-related VOC emissions. The QUADRANT-NRV Series Thermal Oxidation System is designed for use with the low-volume/high-BTU waste gas stream emitted from many landfill gas purification processes. As we utilize our Venturi Burner Package to process the waste ...

The Rockingham landfill gas power station is located in Rockingham, Western Australia and is operated by AGL. After over a decade of operation using the original Jenbacher J320 engines by GE, Clarke Energy will deliver a fourth J320, bringing the total installed ...

Purpose This engineering technical letter (ETL) was written to provide guidance for designers to determine appropriate application of Landfill Off-Gas Collection and Treatment Systems, and to properly design and specify these systems. Applicability This ETL applies to all HQUSACE elements, major subordinate commands (MSC) , districts, laboratories, and field ...

MOST PEOPLE think of landfills as a necessary evil at best, but our current primary method of waste management generates a by-product with significant energy value - landfill gas (LFG). Collection and control of LFG results in significant reductions in greenhouse gas (GHG) emissions. With the greater focus on climate change, a burgeoning market for GHG emission offsets is emerging and landfills ...

In landfill gas utilisation the basic task of the control system is to harmonise three completely independent processes. On the one hand, there is the gas production of the landfill which is inconstant. (From a price point of view, hardly worthwhile to store the gas in a gasometer) On the other side the independent gas utilisation process, which orientates itself to the requirement of the ...

CoGDEM is the trade association representing manufacturers and service providers who are active in the field of gas detection instrumentation and environmental monitoring apparatus. Crowcon Detection Instruments Ltd was one of the founding members of CoGDEM, and in this article their Product Manager of Fixed Systems, Andy Avenell, gives an update on Landfill Gas. Landfill is by far the most ...

HIGH fossil fuel prices and growing concern about global climate change are creating favorable conditions for landfill gas energy (LFGE) projects. Notably, endorsement of LFGE by Federal agencies and many states as a form of “green” power has enabled LFGE developers to earn premiums for electricity marketed through green power programs, and to benefit from expanded federal tax credits for ...

Preparing for the closure and long-term care of a municipal solid waste landfill (MSWLF) can be an inordinate undertaking. Whether public or private, all landfills eventually reach the end of their active lifecycle. Before closure, a landfill must meet a series of criteria as determined by Subtitle D of the Resource Conservation and Recovery Act (RCRA). Following closure, those same regulations ...

In this paper, the Greenhouse Gas (GHG) emissions from an uncontrolled landfill site filled with Municipal Solid Waste (MSW) are compared with those from controlled sites in which collected Landfill Gases (LFG) are utilised by various technologies. These technologies include flaring, conventional electricity generation technologies such as Internal Combustion Engine (ICE) and Gas Turbine (GT) and ...
